The EMPiRE trial: AntiEpileptic drug Monitoring in PREgnancy study Participant Information Sheet You are invited to participate in the study
You are invited to take part in the EMPIRE study. Through this study we plan to find the AED monitoring method that is best and safe for seizure control in pregnancy. The study is entirely voluntary – you do not have to take part, nor do you have to give a reason if you decide not to participate. Before you decide whether or not to take part, it is important that you understand why the study is done and what it involves. Please take time to read this information sheet carefully and talk to others about the study if needed. If there is anything that is not clear, or if you would like more information, you can ask the doctor, midwife or nurse listed above for further advice.
How are mothers with epilepsy on antiepileptic drugs (AED) managed in pregnancy?
Most mothers require long-term treatment with drugs to manage epilepsy, called antiepileptic drugs (AED). These drugs levels in the blood usually fall in pregnancy. This may increase the risk of seizures. Currently, some doctors do regular blood tests to check the level of the drugs in the blood in pregnancy. They offer to increase the dose if the levels fall compared to the last level. This is called Therapeutic Drug Monitoring (TDM). Other doctors do not do regular blood tests in pregnancy. They only increase the dose if seizures worsen or if they occur for the first time in pregnancy. This is called Clinical Features Monitoring (CFM).
Why is this study needed?
We do not have enough evidence to strongly recommend one method of monitoring over the other in pregnancy.
Why have I been asked to take part?
You are a pregnant woman and known to have epilepsy. You are currently on one or more of the following drugs that we are studying: carbamazepine, lamotrigine, levetiracetam or phenytoin. In addition, we would also like to study your views and thoughts on your experiences during the study and the costs involved.
Do I have to take part?
It is entirely your decision to take part or not take part in the study. If you do not wish to participate, you do not have to give a reason and your decision will not affect the standard of care you will receive. Similarly, if you do decide to participate, you are entitled to withdraw from the study at any time, without having to give a reason, and this will not affect the standard of your medical care in any way.
If you do not wish to participate in the monitoring methods part of the study, then you will be approached to provide your views about your experiences of epilepsy and pregnancy for the qualitative part of the study. It is completely upto you to decide to participate in this discussion and your decision will not affect your care.
What will happen to me if I take part?
If you participate in the study, you will be seen as usual every 4-5 weeks up until 6 weeks after you give birth. You will have regular blood tests every 4-5 weeks to check your drug (AED) levels until labour or delivery. Your blood samples will be stored for the lifetime of the trial and for 3 years after the completion of the trial. After this period, the samples will be destroyed.
You will be asked to complete a seizure diary throughout your pregnancy and up to 6 weeks after birth to document the type and frequency of any seizures you may experience, including any side-effects. We will also ask about your mood and general well-being by asking you to fill out a questionnaire at your visits. When your baby is born, the umbilical cord will be cut and is usually disposed of. We will take a sample of blood from the umbilical cord after it has been cut. This will give us information on the level of AED in your baby’s blood at birth.
When your baby is 6 weeks old, at your routine 6 week postnatal appointment, we will assess clinical information about you and your baby. This will be recorded in the medical notes for later use if needed.
The research team may approach you in the future to invite you to participate in a possible long term follow up study about your child(ren)’s development. Funding, ethical approval and consent for specific investigations / examinations will be obtained nearer the time. You can choose whether or not to be contacted.
You may also be asked to complete a questionnaire about any out of pocket expenses (e.g. transport costs, time lost from work or child care costs) you may have incurred when attending the clinics. This will help us find out about the wider cost implications of the two monitoring methods on the health service.
If I take part will I undergo Therapeutic Drug Monitoring (TDM) or Clinical Features Monitoring?
If there is a significant fall in your blood levels of the drug (AED) you will be randomly allocated (like flipping a coin) to receive either Therapeutic Drug Monitoring (TDM) or Clinical Features Monitoring (CFM). We will allocate you randomly to one of these two groups because we do not know which monitoring method is best. If your blood levels of the drug do not fall, you will continue to have 4 weekly blood AED levels monitored. Your doctor or nurse will only inform you of your drug levels if you are allocated to the TDM group or if you specifically request this information. You may sometimes need frequent monitoring if there is a concern about your seizure control.
What will happen to me if I take part in the qualitative part of the study?
Whether or not you choose to take part in the monitoring part of the study, you will be asked to consider taking part in the qualitative study. We are doing this to obtain the views of mothers about the management of their epilepsy while they are pregnant.
If you decide to take part, your care team will pass your contact information to the research team. A member of the research team will contact you to arrange an interview which will last approximately 45 minutes and will take place at a time and place that is convenient for you. We will meet with you once in pregnancy and once after the birth of your baby. You will have one additional visit if you your seizures worsen in pregnancy.
With your permission we will tape record the interviews. All information that is collected during this study will be anonymous and treated with complete confidentiality. Although individual quotations may be used
no individuals will be identified in any publications resulting from this study. Data will be handled, stored and destroyed in accordance with the Data Protection Act (1998).
Are there any benefits for me from taking part in the study?
As we do not know the best method to monitor your drugs in pregnancy, we cannot say if there will be any direct benefit to you and your baby. However, your taking part in this study will help inform decisions about management of pregnant women with epilepsy in the future.
What are the side effects of treatment received when taking part?
You may have side effects related to the type and dose of AED. It is expected that you will remain on your usual AEDs, as it is less likely for these to be changed during pregnancy. If it is necessary to increase/decrease the dose of your AEDs or change them, then the reasons for this will be discussed with you by your epilepsy specialist in the usual way, giving you the opportunity to discuss concerns about the process. If you do feel ill in any way at all, you must tell your doctor.

What are the possible risks and disadvantages of taking part?
The majority of women with epilepsy have healthy pregnancies and give birth to healthy babies. In a small proportion of women with epilepsy there is a slightly higher chance of having a baby with a problem, which may be related to the drugs or the epilepsy itself. The risk of the drugs causing birth defects in an unborn child appears to be greatest during the first three months of pregnancy. If you need to increase the dose of the drug in the study it will only be done after this period. Your doctor or midwife will discuss the risks relating to the type and dose of your drug. Seizures may cause risks to you and your baby and affect your driving licence status. We do not know which method is best for the long term outcome of your baby.
What if new information becomes available?
Sometimes during the course of a research project, new information becomes available about the treatment that is being studied. If this happens, your doctor will tell you about it and discuss with you what to do next. If you decide to withdraw, you and your doctor will decide your future care. If you decide to continue in the study you will be asked to sign an updated consent form.
What will happen if I don’t want to continue with the study?
You are free to withdraw at any time without giving a reason. Your care will not be affected in any way. The data we have collected about you will be analysed, unless you specify otherwise.
Who has organised, reviewed and funded the research?
The trial is funded by NIHR and The Pragmatic Clinical Trials unit (PCTU) at the Queen Mary, University of London will collect and analyse the data and the The National Epilepsy Society for Therapeutic Drug Monitoring Unit, Buckinghamshire will store and analyse blood samples. Queen Mary, University of London are the trial sponsor.
The doctors involved are not being paid for recruiting women into the study. Patients are not paid to take part either, but their help in finding out more about how best to treat epilepsy during pregnancy is much appreciated.
All research in the NHS is looked at by independent group of people, called a Research Ethics Committee, to protect your interests. This study has been reviewed and given favourable opinion by Coventry and Warwickshire Research Ethics Committee.
